The Role of Thermal Modification and Nanofluids in Improving Energy Conversion Efficiency in Heat Exchangers
Abstract
Enhancing energy conversion efficiency in heat exchangers is a critical objective in modern thermal engineering. Thermal modification techniques and the incorporation of nanofluids represent promising strategies to overcome conventional limitations such as low thermal conductivity and limited heat transfer rates. Thermal modification involves optimizing the design and material properties of heat exchangers to improve heat transfer coefficients, reduce fouling, and increase operational stability. Meanwhile, nanofluids engineered colloidal suspensions of nanoparticles in base fluids demonstrate significantly improved thermal properties, enabling superior convective heat transfer performance. This paper explores the combined and individual roles of thermal modification and nanofluids in improving heat exchanger efficiency, examining the underlying mechanisms, practical implementation challenges, and potential for integration into advanced energy systems.
